| message | We deleted the system administrator. We only have one
| user remaining, but that user does not have the system
| administrator capabilities. How can we readd the system
| administrator?
The built-in Administrator account can never be deleted. For
more information search the Windows XP Professional Help and
Support Center Suggested Topic titled: Users overview
However, if your computer is in a workgroup, and you are using
the "friendly logon interface" (not the classic Windows 2000
logon interface) when you create a second user with
Administrative privileges the built-in Administrator account does
not appear. To access the original Administrator account press
the CTRL+ALT+DELETE key combination twice during the friendly
logon interface. For more information see the following
